SHADE-ROLLER.

SPECIFICATION forming part of Letters Patent No. 627,733, dated June 27, 1899.

Application filed November 17, 1898. Serial No. 491,195. (No model.)

To all whom it may concern.-

Be it known that I, EDMUND F. HARTSHORN, of Newark, Essex county, and State of New Jersey, have invented a new and useful Improvement in Shade-Rollers, of which the following is a specification.

My improvement relates to the cup secured to the end of the roller, through which the spindle projects and which forms the bearing for one end of the roller as it revolves around the spindle.

In the accompanying drawings, illustrating my improvement, Figure 1 is a side view of a roller with the cup in position on the latter. Fig. 2 is the same as Fig. 1, with the cup and part of the roller in section. Fig. 3 is a sectional side view of the cup detached, and Fig. 4 is a front view of the cup. 7

The cup ct in my improvement is stamped up from thin metal; and my invention consists in forming the cup when stamped up in such a manner that it will afford a perfect and smooth bearing on the spindle.

In constructing the cup in the process of stamping up from metal the central hole a, through which the spindle projects, is cut out from the metal, leaving a rough edge 19, and in all forms of these cups heretofore used on rollers the spindle has rested on this rough edge, which has thus formed the bearing-surface for the roller, resulting in the wearing of ation of the roller.

the parts and in animperfect and noisy oper- I havefound that it is possible in stamping up the cup to turn the rough edge I) of the central hole to one side of the face or plane of the cup in such a manner that the spindle will rest against the smooth surface a of the metal. As will be seen from Fig. 2, the spindle is in contact with the cup at two pointsat a, where the cup restson the circumference of the spur d, and at a, where the shoulder e presses against the back of the cup. Therefore in turning the edge b of the central hole in order that the smooth-finished surface a of the cup will come in contact with the shoulder c it is necessary that the edge be turned outward or' and thus interfere with the operation of the pawls h, pivoted on the front of the cup, the edge must not project beyond the face of the latter, as will be understood from Figs. 2 and 3.

The-pointed spurs 1', shown as projecting from one side of the journal-bearing, may engage with the rollers to serve in securing the bearing to the roller; but the same is not absolutely essential, as any other s uitable means front face of the cup, and therefore will not interfere with the pawls. Furthermore, by carrying back the projection a some distance I am enabled to form a long bearing a on the spindle, and thus insure a more steady and perfect revolution of the roller.

By the form of construction above described I am enabled to produce a cheap shade-roller cup and yet one that will insure a perfect and noiseless operation of the roller and that will prevent wearof the engaging parts.

It will be observed that by forming the bearing, as described, by pressing a portion of the metal to one side of the face and then in the opposite direction a smooth hole is formed for the journal to pass through, and a concavo-convexo bead or protuberance is made which forms a bearing-surface for a part of the roller and also makes the metal bearingplate stronger than it would otherwise'be. It is also obvious that these advantages are gained, and the construction is the same whether the metal bearing be for the stationary pintle of the roller, as illustrated in Fig. 2 of the drawings, or be the bearing for the other end of the roller, which is formed by the bracket that receives the pintle which revolves with the roller, as is well understood in the art.

I claim A bearing for the journal of a shade-roller formed of metal adapted to be struck up into '2 a e-m shape, said bearing being formed Witha jourjournal, the edge of said flange being in a 16 nal-opening and having the metal around the vertical plane to the bore and on the opposite opening struck up or pressed to one side of face of the bearing to the bead 0r protuberthe face of the bearing into a concavo-conance, substantially as described.
